Field recording - Preamps.
 
Hello.
My current setup for field recording is a couple of Line Audio CM3's into a Roland R-26.

This setup is far from ideal, but it works for the most part (Recording misc. sound effects. Doors, impacts, and so on and so forth).
Ambient recordings are difficult due to noise by heavy gaining. This is to be expected with a budget setup. I've used the CMC3's with other preamps, and I know they don't produce all that noise I'm hearing when I crank up the gain on the R-26. Of course, they're not exactly silent, but I do think the preamps on the R-26 are mostly to blame here. Which again, is to be expected.

So to make a long story short: Is there a portable preamp out there that is less noisy, but reasonably priced? I really want something to improve my sound until I can afford something along the lines of a SD mixer.
Or should I simply just leave it as is for now?

Any advice here would be greatly appreciative.

I was looking into this a while ago and realized that the mixpre-d from SD might work with the ipad. It presented a great option for inputs and being a class compliant usb interface, could be used with computer or ipad, possibly even android slate.

here's a video on a dslr setup

Thanks for the reply!

Actually, it's the MixPre-D I'm saving up for. Where I live, it's over 1000$.
I'm looking at the Azden FMX-22 as a midway stop. Think it'll do me any good?

I've learned that good gear is worth it and getting what you really don't want comes up over and over again. Just save for what you want and even though it takes longer, it'll be worth it. especially SD stuff, it's rock solid.

Don't touch the azden, look around for second hand sound devices gear head over to jwsoundgroup.net people often have mixers for sale there.

You can get used Wendt mixers pretty cheap - they sound pretty nice IMO.

Cheers!

Check on ebay. Not in the same league than SD but still good and very cheap these days.

Thank you all for your input!
I'm currently looking into those Wendt mixers.

I think that the CM3 (16dBA noise) might be your main noise "contributor" when trying to record very quiet sources. The R-26 seems to have decent preamps for a hand-held (EIN -124dBu A-weighted @ max gain). Just to put things in perspective, a Rode NT1-A (5dBA) has a -118dBu noise floor.

If you do decide to buy a portable preamp, Naiant's tinybox has good specs and isn't very expensive.

I regularly use a r-26 with oktava's mk012 and the preamps suck really bad...
Connected to my roland interface the floor noise difference is abismal, I'll record it the next time I use them.

It's not uncommon for cheap(er) preamps to have much more noise with low gain settings. Best way for the op to know for sure, is to choose a typical gain range for the job and test it using a terminated xlr plug (use a 150ohm resistor).

Are preamps really horribly loud and A/D conversion bad on cheaper bundle such as the Olympus LS-100 ? I'd like to get a very portable MS rig for field recording, ambience and effects but obviously my budget is limited.

Thanks a lot

It depends on what you're recording. For low level ambiences, you need a recorder with lots of clean gain. I guess Sound Devices (' price point) is your reference, but last gen. Zoom recorders do pretty good too. Also Sony's D-50 is widely used. But I never heard a portable recorder with high quality onboard mics.
LS-100 seems to only have a low & high gain setting while it does have manual record-level adjustment. But I never worked with it.

Another thing: I think hand-held portability and easy operating do contradict, also when already holding a blimp with a pair of MS mics.
Nothing beats a frontside operated recorder in a bag (like Zaxcom, SD & Zoom F4/F8)
Lastly, the quality of the headphone amp should be considered, low priced recorders often have crappy ones. As a field recordist, you'd want clean, high quality monitoring.

Check out the new MixPre-3 from SD when it comes out. Super-small and SD hasn't made any gear with rubbish inputs so far. Wait till it comes out.

That looks EXACTLY what I need.

Any idea of both timing and pricing of the release ?

Thanks a whole bunch.

Oye. Other question. What's your opinion on fur (Ry-021901) vs. case (Ry-010904) windshields ? How will they alter my field recording ?

Cheers from Spain

The windjammer you mention is to be put over a basket in high wind situations. It’s just a standard tool in a kit, used outside when windspeed reaches 3 to 4 Bft (> 25 km/h or 12 mph). A windjammer will take away some energy and high freqs, but if maintained well (regulary brushed, kept dry, stored inside out), it won’t affect sound quality that much.
The basket itself also lowers wind pressure, but only works up until 3 Bft. The mic suspension acts as a mechanical filter, it blocks microphone movement & handling noises.

Referring to your plan of capturing ambiences and sound effects, I would advice putting the basket on a tripod whenever possible (instead of holding it in your hand).
Using a twin microphone MS set doubles the weight on the suspension. I guess only newer type baskets like the Rycote Cyclone with Conbox or it’s competitor, French brand Cinela are really silent when moving a handheld (twin mic) MS-set.
